You may have been wondering what has taken me so long to get this post up. Well, even bloggers need some vacation now and again. But now I am back and raring to go!
I am still reading The God Delusion, but I wanted to go ahead and start the discussion. Let me begin by saying that I do respect Richard Dawkins as a biologist. In many ways he has made the evolutionary process more accessible to the everyday man and generally increased the public’s interest in science. However, when Dawkins moves beyond biology into philosophy, his logic begins to acquire holes.
For those of you who don’t know, my wife and I lived in Oxford, where Dawkins resides, last autumn and winter. I was then studying for a Master’s in Economics, but that is a whole story on its own. Needless to say, I decided that the field of Economics was not the best fit for me, which is why we are now back in America. But while we were there, we had the privilege of partaking in the general philosophical atmosphere of many an Oxford evening. I was lucky enough to attend a few lectures given by members of the philosophy faculty discussing bioethics and science in general. I was surprised to hear that among the philosophers at Oxford, many found Dawkins’ arguments unimpressive, hardly worthy of a serious response.
So Dawkins has failed to win over even those within his own town who, at least by academic standards, are masters of argument and logic. But most people are more easily convinced by someone like Dawkins speaking with authority. So I do think his arguments deserve a response. I would like to begin my own response with some thoughts on Chapter 4 in The God Delusion, “Why There Almost Certainly Is No God.”
Dawkins basic points in this chapter are as follows:
Any argument for a designer is rooted in an attempt to explain complexity. However, we have found that natural selection is capable of explaining the rise of complexity from simple precursors. So where we thought we needed a designer to explain the evolution of life, we were wrong. He then points out that physics has not yet found its unifying, explanatory principle (a principle analogous to natural selection). But Dawkins thinks that the multiverse theory may be on the right track. He concludes that natural selection has “raised our consciousness” to realize that nature itself is capable of producing all of these complex wonders, and that we should now see there is no need for a God; nature is capable of doing everything herself. We just haven’t yet figured out how it works in physics.
This argument is simply the inverse of the creationist argument. Creationists say: “We can’t explain nature, so there must be a God.” Dawkins says: “We can explain nature, so there must not be a God.” Neither of these arguments is logical. The existence or nonexistence of God in no way follows directly from our ability either to explain or not explain how nature works. The only thing that we can show as a result of being able to explain nature scientifically is that if there is a God, he is not forced to interact with nature. But even that does not mean that if God exists that he must not interact with nature.
Now it is obvious that Dawkins is focused on addressing ID advocates, so I can understand his desire to prove them wrong, but proving the IDers wrong is not the same as proving God doesn’t exist. The latter requires a much more rigorous proof, and I don’t think Dawkins provides one. At least, by the time he finishes his discussion of “Why There Almost Certainly Is No God,” he has not done so.
The first key omission in the chapter is a discussion of final cause. I talked about this some in my post on the Anthropic Priniciple and elaborated in the comments, but it wouldn’t hurt to have a quick rehash. Dawkins seems to think that if we can explain the origins of this universe, perhaps by a multiverse theory, that we would have a final cause therein. But just as Dawkins asks who designed the designer, I would ask what came before the multiverse or how did the multiverse begin. If there really was some sort of infinitely existing multiverse that stretched back into eternity past, then science would never be able to delineate it. Anything that is causeless is beyond what we know in nature. If we found such an infinite material thing in nature (not infinite going forward, but infinite going backward), science could not explain it.
Dawkins speaks as if this multiverse is a simple theory, and that God is too complex to be probable, but anything that has always existed is already on a plane of complexity much higher than anything we have ever observed. And since all of the natural sciences operate on the fact that 100% of our observations have a natural cause, then I am very suspicious of anyone proposing that something material could have no cause. That is contrary to all science that has ever been done. If I am going to accept the idea that anything has existed forever, it is certainly not going to be something material.
The other possibility is that something, whether the Big Bang, the multiverse, or something else, was really the absolute first thing to exist. But this idea is just as causeless as an infinite multiverse. If some material came first, it too would lack an explanation for how it arose. This would defy science just as much as anything else. In fact, this problem is precisely why things like the multiverse have been proposed. We have no evidence whatsoever for a multiverse, but science wants desperately to explain the origins of the Big Bang. Surely the singularity hadn’t just been sitting there forever! But either there was a first or there was something infinite. Neither can be explained by natural means. So to explain a final cause, we must consider knowledge other than just science. Either that, or we must accept that we are always incapable of knowing.
This gaping hole in the argument does not leave me satisfied with Dawkins’ conclusion from science that there must be no God. However, deciding that Dawkins’ argument against the existence of God is not strong does not mean that a God exists. That is, we cannot apply Dawkins’ own logic and say, “Dawkins is wrong; therefore, God exists.” I do not accept that science can disprove God; nor do I accept that science can prove God. So we must operate on other information available to us.
This brings us to the second big fault in Dawkins’ argument. He (as far as I can tell) ignores many other relevant pieces of information in his quest to disprove God. Now I know that in subsequent chapters Dawkins is going to address specific problems with religion, so forgive me if he addresses this later and I have not reached it yet. If that is the case, I will revise this article upon reaching it. But I feel that Dawkins’ scientific approach is very limiting. I might agree with Dawkins’ conclusion if I had to make my decision based only on science, but that is not the case, and I believe evidence from other realms makes belief in God completely rational.
In my opinion, one of the strongest evidences for something beyond the material world is the existence of a moral law. I do not mean to explain altruism, for which I know Dawkins has a biological argument. We all ascribe to some sort of moral law when we say that something is “not fair.” We all agree that harming an innocent child or spreading false rumors is bad. Sometimes you can even see this moral law in action from the mouths of criminals. Someone who has committed a heinous crime and has come to realize just how terrible the crime was can sometimes be heard saying (and not simply in court) that they “deserve punishment.”
In some simple form, we all recognize this moral law, and importantly, it is external to us. We do not alter it, and it does not have a material cause. Where does this law then come from? It must come from something outside of the material realm. But really I have taken this whole argument from C.S. Lewis, and he is much better at explaining it than I am. You can get a better picture by reading the first five or six chapters in Mere Christianity (they are short chapters). I’m not entirely sure how legal this is, but you can find the whole book online here, so please check it out.
While I think it is possible that altruism could be influenced by biology, I do not think the moral law is a byproduct of genetics. So that is just one philosophical argument for the existence of God, one that is unmentioned in Dawkins’ chapter concerning arguments for the existence of God.
In conclusion, I do not find Dawkins’ argument against the existence of God very convincing. It is severely limited by only discussing scientific reasoning, and the logic that he uses as a result of the science is very faulty. And even from a scientific standpoint, he does not even attempt to explain some of the most difficult questions about final cause.
As a Christian, I also obviously believe that the Bible provides reliable, rational evidence for God. Dawkins does address this view in a rather vitriolic fashion, so in my next post I will begin to discuss his understanding of the Bible and where I think his conclusions are inaccurate. In particular I will talk about the Old Testament, miracles, and the character of God.
